Abstract

Current approaches to integrating industrial ecosystems, for instance integrating automation functions across different vendors, lack efficiencies and capabilities. For example, system integrators are often required to develop special software that functions as a proxy or adaptor between different systems. In such cases, the proxy or adaptor is often specific to a particular set of equipment or vendors, and which can limit reusability, among other technical drawbacks. Embodiments described herein overcome one or more of the described-herein shortcomings or technical problems by providing methods, systems, and apparatuses for automatically generating connecters that enable interoperability between different ecosystems in automated industrial systems, and that define semantics that are specific to a given ecosystem. Further, such connectors can be re-used by the given ecosystem.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS
• This application claims the benefit of U.S. Provisional Application Ser. No. 62/913,372 filed on Oct. 10, 2019, the disclosure of which is incorporated herein by reference in its entirety.
BACKGROUND
• Automation systems can be used to control the operation of machines and other components in a systematic manner. Automation systems can include various automation domains such as factory automation, process automation, building automation, energy automation, and the like. Automation systems can also include equipment from multiple vendors. In some cases, equipment and machines within an automation system may use varying mechanisms associated with their respective ecosystems, such as varying runtime environments, protocols, and programming languages (e.g., vendor-specific programming languages). By way of example, automation functions are often platform specific and/or are implemented in a proprietary manner. Thus, generating an automation function that is interoperable with other automation functions can be cumbersome and time-consuming.
• Automation systems typically interact with the physical world through sensors to retrieve and monitor the real world's state. Automation systems also typically interact with actuators to change and control the real world's state. In some cases, the digitalized state of physical entities is preserved in a digital twin, which can refer to a process image of the current state of a physical system. It is recognized herein, however, that standards are lacking concerning how to build and maintain digital twins. Thus, often each vendor of automation equipment establishes vendor or product specific interfaces and tools that enable automation functions to interact, via digital twins, with the real world. As a result, in some cases, system integrators and application engineers of automation systems have to deal with a vast variety of digital twins that may each provide a respective proprietary set of interfaces and tools.
• Thus, it is further recognized herein that current digital twins lack capabilities and efficiencies. By way of example, shortcomings related to out-of-the-box interoperability and exchangeability among today's digital twins inhibit digitalization.
BRIEF SUMMARY
• Embodiments of the invention address and overcome one or more of the described-herein shortcomings or technical problems by providing methods, systems, and apparatuses for automatically generating connectors that define semantics specific to particular ecosystems, and that enable interoperability between different ecosystems in automated industrial systems.
• In an example aspect, a method can be performed in an industrial system that comprises a plurality of ecosystems that define respective physical assets and automation equipment configured to control the physical assets. The method can include receiving an interface file that defines an interface description language. Based on the interface file, a generator or modular connector printer can generate a first integration connector that is specific to a first ecosystem of the plurality of ecosystems. The first integration connector can be used to trigger an action, from the first ecosystem, performed at a second ecosystem of the plurality of ecosystems. As an example, the action can include retrieving information from the second ecosystem, by the first ecosystem. The information can define semantics associated with the first ecosystem. The information and the semantics can be displayed on a human machine interface of the first ecosystem. Alternatively, or additionally, the action can include one or physical assets of the second ecosystem performing a task defined by the first ecosystem. Further, based on the interface file, a second integration connector can be generated that is specific to the second ecosystem. The integration connector can be plugged to the second integration connector, such that the second integration connector is also used to trigger the action performed by the second ecosystem.
• In an example, the first integration connector can run on a first machine, the second integration connector can also run on the first machine, such that the first integration connector is plugged directly to the second integration connector. In another example, at runtime, a first communication connector can be inserted between the first integration connecter and the second integration connector, such that communication between the first integration connector and the second integration connector hops over a machine that hosts the first communication connector. In yet another example, at runtime, a second communication connector can be inserted between the first communication connecter and the second integration connector, such that communication between the first and second integration connectors hops over multiple machines and ecosystems. The first integration connector can also be used to trigger another action, from the first ecosystem, performed at a third ecosystem of the plurality of ecosystems.
• The action can be triggered using a third integration connector that is specific to the third ecosystem.

DETAILED DESCRIPTION
• Automation functions, automation equipment, and automation engineering systems and tools are often locked into vendor-specific ecosystems. For example, it is recognized herein that automation ecosystem vendors often focus on optimizing their own environment (e.g., hardware, software, runtime, engineering and development tools), such that there is often little support for integrating their environment with competitors or third party ecosystems.
• Referring toFIG. 1, anexample automation system100 defines a plurality of ecosystems or domains. In particular, theexample system100 can include a first orproduction ecosystem102, a second orproduction ecosystem104, a third orproduction ecosystem106, and a fourth orproduct ecosystem108. The exampleindustrial system100 can define or be part of a factory, such as a factory for manufacturing or assembling various products. In accordance with the example, theproduction ecosystem102 includes agantry station112, theproduction ecosystem104 includes arobot station114, and theproduction ecosystem106 includes atransport station116, though it will be understood that the production ecosystems can include any stations as desired. It will further be understood that while four ecosystems of theexample automation system100 are illustrated, automation systems described herein may include any number of ecosystems, and all such systems are contemplated as being within the scope of this disclosure.
• Each ecosystem can include physical assets that can be controlled by automation equipment configured to control the respective physical assets. Such automation equipment can include one or more programmable logic controllers (PLCs)101. By way of example, the gantry station can include a gantry PLC101a,the transport station can include a transport PLC101b,and therobot station114 can include a robot PLC101c.The PLCs, and thus the automation equipment, may be specific to one or more physical assets in the respective ecosystem. Theautomation system100 can be configured to perform various automation functions.
• Still referring toFIG. 1, it is recognized herein that when automation functions are developed within the same ecosystem (e.g., SIMATIC), those automation functions can, in some cases, be easily integrated with each other so as to interoperate with each other. In contrast, when automation functions are developed for different ecosystems, the automation functions may be incompatible with one another, such that they do not interoperate with each other without significant integration effort. By way of example, vendors might provide some open programming (e.g., WinCC ODK) or communication interfaces (e.g., OPC-UA server) that enables other ecosystems to share and exchange (e.g., consume or provide) information across ecosystems. It is recognized herein, however, that this may require application engineers or system integrators to develop software (e.g., glue code) that maps open interfaces of one ecosystem into open interfaces of another ecosystem. It is further recognized herein that such code may be specific to a given use case, and thus is not reused. In particular, for example, development of such glue code can include integrating existing protocol stacks or developing protocol stacks; crossing of language boundaries; converting data types for a selected protocol stack (e.g., layout, versioning); adopting an execution model of a selected protocol stack (e.g., threading, data integrity, timeout); developing a state machine to manage a user-defined application protocol (e.g., connection(loss) management, notification/events); and/or using generic interfaces (e.g., read/write data) that require mapping to domain context.
• To further illustrate technical problems related to current approaches,FIG. 2 shows anexample system200 that includes theexample ecosystems104,106, and108. As described herein, in current approaches, automation vendors often focus on the perfection of their own first ecosystem, and add communication drivers (e.g., COM drivers in WinCC) and openness interfaces (e.g., scripting, ODK), to facilitate glue code development for integrating incompatible automation functions. Referring toFIG. 2, in theexample system200, theproduct ecosystem108 can communicate with theproduction ecosystem104 via a point-to-point connection202 that has been implemented between theecosystems108 and104. In other examples, ecosystems can employ standards (e.g., OPC-UA or DDS) so as to enable some integration. It is recognized herein, however, that ecosystems that do not support a given standard often cannot interoperate with an ecosystem that employs the given standard. For example, in theexample system200, theecosystem108 and theproduction ecosystem106 each support a standard204 that enables them to communicate with each other via aconnection206 between theecosystems108 and106. In contrast, thesecond ecosystem104 does not support the standard204, and thus is not able to communicate with thethird ecosystem106.
• Thus, still referring to theexample system200 of FIG,1, in order to integrate automation functions in the different ecosystems, connectors, which can be referred to as glue code, can be developed. It is recognized herein, however, that these connectors are typically suited for point-to-point integration so as to define monolithic connectors that enable interoperability of only two ecosystems. Thus, in some cases, new connectors are developed each time an additional ecosystem is integrated within thesystem200. Further, it is recognized herein that such connectors are often generic and therefore difficult to use because, for example, they do not carry semantics about the respective domain. By way of example, an generic connector might support read/write/subscribe topics, but not read/write/subscribe topics for a specific operation, such as a change in oil pressure or the like. Similarly, by way of further example, generic connectors might not support interface-oriented access (e.g., Request/Reply pattern) or topic-oriented access (publish/subscribe pattern) to another ecosystem.
• Referring now toFIG. 3, in accordance with various embodiments, a generator module ormodular connector printer302 can generate connectors as needed. Using themodular connector printer302, automation function developers can define interfaces and/or topics with semantics and domain specifics that are user-friendly. Glue code, or a connector, can be generated and linked at runtime, which can define late binding, so as to map a definition across ecosystems. In various examples, themodular connector printer302 can generate one orcommunication connectors304 and/or one ormore integration connectors306. Thecommunication connector304 can provide a generic communication interface for using various existing protocol stacks, such as, for example and without limitation, HTTP, MQTT, and S7-DOS. In an example, thecommunication connector304 defines a generic interface or communication abstraction that is developed once per supported protocol stack. Thus, thecommunication connector304 can be used to transport information or communication from one computational node to another. In some cases, multiple communication connectors can be linked together, such that communication between two integration connecters hops over multiple machines and ecosystems. Theintegration connector306 can map a natively accessible easy-to-use interface and topic having domain semantics to a generic communication interface defined by thecommunication connector304. In some cases, a givenintegration connector306 can be generated or pre-coded based on a user-defined interface or topic description. In an example, oneintegration connector306 is generated per supported ecosystem. Thus, referring toFIG. 3, in accordance with an example, theintegration connector306 can be generated once per ecosystem, such that afirst integration connector306acan be generated for theproduct ecosystem108, asecond integration connector306bcan be generated for theecosystem102, and athird integration connector306ccan be generated for theecosystem104. In particular, thefirst integration connector306acan be used for theecosystem108 to interoperate with theecosystem102 or theecosystem104, or any other ecosystem. In various examples, thecommunication connector304 can be combined with any type ofintegration connector306, in some cases, depending on the availability of protocol stacks for the given ecosystems. In some cases,integration connectors306 can be directly linked with each other without thecommunication connector304, for instance, when two or more integration connectors run on the same machine.
• Referring also toFIG. 1, various automation systems described herein can include anabstraction layer110 that abstracts (exposes) automation functions that can be performed by the automation equipment and the physical assets. In accordance with various embodiments, theabstraction layer110 can include the generator module or theconnector printer302. Theabstraction layer110 can execute in a runtime environment, so as to provide interfaces to the automation functions. Theabstraction layer110, and thus theconnector printer302, can be implemented on a server, a cloud-based computing environment, a vendor-specific runtime platform environment, or other industrial computing system, such as a computer system510 (seeFIG. 6).
• Theabstraction layer110 can abstract various functional characteristics, which can define automation functions, from the automation equipment. The automation functions can be soft-wired together, such that theabstraction layer110 can serve as an intermediary between various development environments and various automation equipment. Thus, theautomation system100, in particular theabstraction layer110, can provide functionality corresponding to a physical component, for instance the automation equipment and/or physical assets. In doing so, developers can operate in one or more development environments, for instance a development environment of their choice, to use various automation functions, via theabstraction layer110, and the automation functions can be performed by the automation equipment and physical assets. In particular, theabstraction layer110 can enable automation functions from different domains to interoperate with one another. The development environments may define one or more languages or platforms, such as Java, C, Matlab, Python, Siemens Totally Integrated Automation (TIA) Portal, or the like. Thus, various development environments can utilize various automation equipment from various domains, via theabstraction layer110.
• Referring also toFIG. 4, anexample system400 includes theexample ecosystems102,104,106, and108, so as illustrate an example of interoperability using connectors across multiple ecosystems. As an example, thegantry station112 can be controlled by automation equipment that is programmed in a second programming language that is different than the first programming language of theproduct controller118. By way of example, thegantry PLC101amay define one or more programmable logic controllers from Siemens (e.g., SIMATIC S7-1517) that are programmed in the second programming language (e.g., IEC61131 in a TIA Portal engineering environment). Continuing with the example, therobot station114 can be controlled by automation equipment from Kuka, such as a Kuka robot PLC101cthat is programmed in a third programming language (e.g., Java-based) that is different than the first and second programming languages. Thetransport station116 can be controlled by the transport PLC101b,which can be from MagneMotion and provide control nodes programmed in a fourth programming language (e.g., Web or C++ based). Thus, without being bound by the specific examples, the functionality of each of the PLCs101a-candproduct controller118 can be programmed with languages and tools supported by the equipment vendor of its respective ecosystem. Further, each of the PLCs101a-cand the PC-basedproduct controller118 can each implement one or more functions that are called by one another. Thus, the various PCS101a-cand the PC-basedproduct controller118 need to interact with each other, in various use cases.
• In another example, theproduct ecosystem108 defines a WinCC consumer of one or more automation functions. Further, in the example, theproduction ecosystem102 can include aBeckhoff PLC101aand theproduction ecosystem104 can include a SIMATIC PLC101bthat each provide the same interface/topic as each other. Theproduct ecosystem108 can use theintegration connector306ato access theproduction ecosystem102 or theproduction ecosystem104. Thus, the consumer can use the same integration connector to access PCLs in different ecosystems, and the code on the consumer (e.g., within the WinCC application) can be agnostic of the particular ecosystem that provides an interface or topic. In various examples, theintegration connector306ccan be used by theproduction ecosystem104 regardless of whether an interface or topic is invoked by theproduct ecosystem108 or theproduction ecosystem106. Similarly, anintegration connector306d can be generated that is specific to theecosystem106. Thus, code on the provider side (e.g., SIMATIC PLC) can be agnostic of the ecosystem that uses an interface or topic. Thesystem400 can also include one ormore communication connectors304, for instance anHTTP communication connector406 or an S7-DOS communication connector408, which can be combined to map, for example, from theproduct ecosystem108 to theproduction ecosystem104. Alternatively, or additionally, the S7-DOS communication connector408 can connect theintegration connector306aof theproduct ecosystem108 with theintegration connector306bof thefirst production ecosystem102.
• With continuing reference toFIG. 4, and referring also toFIG. 1, in an example, eachproduction ecosystem102,104, and106 can offer or provide various production skills so as to perform various industrial tasks, such as for example pick and place, transport, assembly, or the like. Theproduct ecosystem108 can use or consume one or more of theproduction ecosystems102,104, and106 to assemble or manufacture one or more products. Example products include various products produced in production plants having PLCs, such as, without limitation, vehicle parts (e.g., tires, doors, engine mounting), food and beverages (e.g., mixing ingredients, controlling robots for bottling plants), pharmaceutical products, or the like, though it will be understood that any product that requires machine operations can be produced in accordance with embodiments described herein, and all such products are contemplated as being within the scope of this disclosure.
• in some cases, thegantry station112,robot station114, andtransport station116 can each be provided from different equipment vendors, which can create interoperability issues addressed herein, among other challenges. By way of example, theproduct ecosystem102 can include automation equipment, for instance aproduct controller118, that is associated with a product that is assembled or manufactured by theindustrial automation system100. By way of example, theproduct controller118 can be PC-based, and can be programmed by a first programming language, such as WinCC for example. Theproduct controller118 can perform various activities during the lifecycle of a given product. For example, during a design state, a desired state of a given product can be established within theproduct controller118. The desired state may refer to the overall condition of a product or machine during or after production. The desired state may indicate various information such as, for example, absolute position information, position information relative to other physical assets, temperature limitation, stress level limitations, or the like. The desired state may be determined from inputs to theproduct controller118 such as, for example and without limitation, a Bill of Process (BOP), Bill of Materials (BOM), properties of the materials, and 3D models (e.g., CAD models) or other physical models of the product.
• In some cases, aspects of the product may be manually defined based on user input. Referring also toFIG. 5, a system integrator may implement automation functions via a user interface, for instance via a human machine interface (HMI)500. In an example, therobot station114 defines an automaton function that is able to move a robot (e.g., IRobotMove), track the position of the robot, and store the position of the robot in a topic (e.g., AxisPosition). A user, for instance a system integrator, can use the robot, for instance a Universal Robot, via the WinCC application and theHMI500. In particular, via theHMI500, the user in theproduct ecosystem108 can monitor an axis motion of the robot, and move the robot to predefined positions. Such positions can be defined atexamples inputs502 of theHMI500. Themodular connector printer302 can receive interface definitions and topics, and can generate connectors based on the interface definitions and topics. For example, a user can define an interface description language (IDL) file504 that includes domain semantics that define an interface (e.g., IRobotMove) and topic (e.g., AxisPosition). Based on theIDL file504, themodular connector printer302, which can also be referred to as a generator module, can generateintegration connectors306, in particular theWinCC integration connector306a.TheWinCC integration connector306acan define tags, for instance an Axis Position. The WinCC integration connector can further define an application programming interface (API), such as a Java Script APT (e.g., IRobotMove (x, y, z)). TheWinCC integration connector306acan thereafter be imported into theproduct ecosystem108, such that the related tags and API are viewable in theHMI500. Thus, themodular connector printer302 can generate interfaces and topics that are easy to use and that include semantics that are specific to the given domain.
• Referring toFIG. 5, in an example, a user of theproduct ecosystem108 can subscribe to theproduction ecosystem104, via theWinCC integration connector306a, without manually controlling the PLC101cof theproduction ecosystem104. In particular, for example, theproduct ecosystem108 subscribe to a topic of theproduction ecosystem104, such that the topic publishes when an associated value changes. In various embodiments, the subscriber (e.g., product ecosystem) can subscribe to the topic without knowledge of where the topic is published. Further, theintegration connectors306 can be generated based on a user-defined file, for example, that includes Java script or the like. When the communication link is formed, thecommunication connector304 can be inserted between theintegration connectors304 such that thecommunication connector304 can be inserted at runtime. A givenintegration connector306 can be generated for any ecosystem that defines an open interface. Thus, integration connectors can be generated for target products (e.g., a PLC manufactured by a different vendor) in different ecosystems without changing firmware or otherwise adjusting the target product.
• Still referring generally toFIG. 5, a user, for instance an automation function developer, can define interfaces and topics in theIDL file504. In an example, based on the definitions in theIDL file504, theconnector printer302 can generatevarious integration connectors306. Thus, in some cases, connectors between ecosystems are generated without having to develop glue code. Such integration connectors can include interfaces and topics that define semantics that are specific to the associated domain, such that automation function developers can focus on business logic development, rather than interoperability. In particular, for example, automation functions can be developed in the language and/or environment of choice. Further, as shown in theexample system400, communication connectors can be combined and linked so as define communication links that hop over multiple physical systems, for example, based on the availability of communication protocols on each node. Thus, in accordance with various embodiments, connectors can be applied in various patterns as an add-on to any ecosystems based on existing interfaces. Further, such connector modularization can enable the integration connectors to be re-used across a range of communication connectors.
• Thus, as described herein, in an example aspect, a method can be performed in an industrial system that comprises a plurality of ecosystems that define respective physical assets and automation equipment configured to control the physical assets. The method can include receiving an interface file that defines an interface description language. Based on the interface file, a generator or modular connector printer can generate a first integration connector that is specific to a first ecosystem of the plurality of ecosystems. The first integration connector can be used to trigger an action, from the first ecosystem, performed at a second ecosystem of the plurality of ecosystems. As an example, the action can include retrieving information from the second ecosystem, by the first ecosystem. The information can define semantics associated with the first ecosystem. The information and the semantics can be displayed on a human machine interface of the first ecosystem. Alternatively, or additionally, the action can include one or physical assets of the second ecosystem performing a task defined by the first ecosystem. Further, based on the interface file, a second integration connector can be generated that is specific to the second ecosystem. The integration connector can be plugged to the second integration connector, such that the second integration connector is also used to trigger the action performed by the second ecosystem.
• As further described herein, in an example, the first integration connector can run on a first machine, the second integration connector can also run on the first machine, such that the first integration connector is plugged directly to the second integration connector. In another example, at runtime, a first communication connector can be inserted between the first integration connecter and the second integration connector, such that communication between the first integration connector and the second integration connector hops over a machine that hosts the first communication connector. In yet another example, at runtime, a second communication connector can be inserted between the first communication connecter and the second integration connector, such that communication between the first and second integration connectors hops over multiple machines and ecosystems. The first integration connector can also be used to trigger another action, from the first ecosystem, performed at a third ecosystem of the plurality of ecosystems. The action can be triggered using a third integration connector that is specific to the third ecosystem.
